The conspiracy led a 28-year-old man to bring an assault rifle to the restaurant on Sunday, police said. They said the gunman was looking to investigate the story himself.

“Until #Pizzagate proven to be false, it will remain a story,” Flynn Jr. posted to Twitter. “The left seems to forget #PodestaEmails and the many ‘coincidences’ tied to it.”

That’s when Tapper apparently began to direct message Flynn Jr. on the app, asking for one piece of evidence proving that the pizza shop was “the site of a satanic pedophilia cult.” Those direct messages were posted by another user.

“Michael — the police called pizza gate a fictitious conspiracy theory tonight,” Tapper wrote. “Does someone have to die before you take this s— seriously. Spreading this nonsense is dangerous.”

“I want it to be false,” Flynn Jr. responded.

“It is not the site of a satanic pedophilia cult,” Tapper shot back. “It is a f—— pizzeria. Show me what you’re talking about that proves a satanic pedophilia cult. Your tweet is wildly irresponsible. Listen to me. You are going to get someone killed. Maybe an innocent child. For what??????”

Flynn Jr. later posted another screenshot of a DM thread with Tapper with the caption, “Want evidence??? I must’ve really hit a nerve.”
